小麦花青素合成调控机制与育种研究进展OA

Anthocyandins are the key bioactive components responsible for the purple/blue grains in wheat and play an important role in enhancing nutritional quality owing to their strong antioxidant ac-tivity.This review discusse the chemical characteristics and health-promoting effects of anthocyanins,comprehensively elaborates on the functions of key structural genes in the anthocyanin biosynthetic pathway and the intricate regulatory network formed by transcription factors such as MYB,bHLH,and WD40.It summarizes the application of both conventional breeding techniques and genetic engi-neering technologies in breeding anthocyanin-enriched wheat varieties in China,and proposes a novel strategy of intelligent molecular design breeding that integrates genomic selection,multi-omics big da-ta mining,and artificial intelligence(AI)-based predictive models.This review aims to provide a solid theoretical foundation and technical support for breeding new functional wheat varieties that synergis-tically combine high and stable yield with enhanced nutritional value.
